An investigation was undertaken after the FBI discovered numerous online advertisements for counterfeit drugs closely resembling genuine Viagra and Cialis tablets, according to a federal Department of Justice news release.

On Nov. 1, 2012, law enforcement officers, posing as customers and responding to a Craigslist advertisement, set up a controlled purchase from Eversoll and a co-defendant. The FBI has since seized a total of 5,652 counterfeit pills of Viagra and 495 counterfeit pills of Cialis, authorities said.
